title: Streptomyces albus: a new cause of hypersensitivity pneumonitis.
abstract: Hypersensitivity pneumonitis is an immunologic lung disease known to be induced by the inhalation of either organic or inorganic antigens, and it may thus be associated with a variety of occupations and microorganisms. To identify an inciting allergen, environmental, bacteriologic, immunologic, and bronchial challenge studies must be employed. These techniques were used to demonstrate that a bacterium uniformly present in processed dirt, Streptomyces albus, was responsible for a biopsy-proven case of hypersensitivity pneumonitis.
